Objective To compare the postoperative enhanced recovery outcomes of lobectomy performed under non-intubated video-assisted thoracic surgery (NIVATS) versus intubated video-assisted thoracic surgery (IVATS). Methods Computerized searches were performed in the following databases: China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Information, China Biomedical Literature Database (CBMdisc), Web of Science, Clinicaltrials.gov, The Cochrane Library, EMbase, and PubMed. We collected randomized controlled trials (RCTs) and observational studies comparing NIVATS and IVATS. The search period extended from the inception of each database to April 1, 2023. Two independent researchers screened the literature and assessed study quality. Results A total of 14 studies were included, comprising 4 RCTs, 7 retrospective cohort studies, and 3 propensity score matching studies, involving 1 840 patients. Meta-analysis results indicated that, compared to IVATS, NIVATS was associated with significantly shorter operative time [MD=–13.39, 95%CI (–20.16, –6.62), P<0.001], shorter length of hospital stay [MD=–0.81, 95%CI (–1.39, –0.22), P=0.005], shorter chest tube duration [MD=–0.73, 95%CI (–1.36, –0.10), P=0.02], shorter postoperative anesthesia recovery time [MD=–20.34, 95%CI (–26.83, –13.84), P<0.001], and shorter time to oral intake after surgery [MD=–5.68, 95%CI (–7.63, –3.73), P<0.001]. Furthermore, NIVATS showed a lower incidence of postoperative airway complications [OR=0.49, 95%CI (0.34, 0.71), P<0.001] and less total chest tube drainage volume [MD=–251.11, 95%CI (–398.25, –103.98), P<0.001], all contributing to significantly accelerated postoperative enhanced recovery for patients. Conclusion NIVATS is a safe and technically feasible anesthesia method in thoracoscopic lobectomy, which can to some extent replace IVATS.

OBJECTIVE: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pain in patients undergoing modified radical mastectomy for breast cancer. METHODS: A total of 140 female patients scheduled for unilateral modified radical mastectomy for breast cancer undergoing general anesthesia were randomized into a TEAS group (70 cases) and a sham TEAS group (70 cases, 2 cases dropped out). Patients in both groups received TEAS or sham TEAS at bilateral Neiguan (PC6), Zusanli (ST36), and Danzhong (CV17), respectively, from 30 min before anesthesia induction until the end of surgery, and on 1st, 2nd, and 3rd days after surgery for 30 min a time, once a day. On 1st, 2nd, and 3rd days after surgery, the pain visual analogue scale (VAS) score was observed; on 3, 6, 12 months after surgery, the incidence rate of chronic pain was observed; before surgery, and on 1st, 3rd, and 7th days after surgery, the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 were detected; the number of analgesia pump press, rescue analgesia, and the occurrence of adverse reaction after surgery were recorded in the two groups. RESULTS: In the TEAS group, the VAS scores on 1st and 2nd days after surgery, and the incidence rates of chronic pain on 3 and 6 months after surgery were lower than those in the sham TEAS group (P<0.05). On 1st, 3rd, and 7th days after surgery, the serum levels of TNF-α, IL-6, and IL-10 were increased compared with those before surgery in both groups (P<0.05, P<0.01); the above indexes in the TEAS group were lower than those in the sham TEAS group (P<0.05). The number of analgesia pump press and the incidence rate of rescue analgesia after surgery in the TEAS group were lower than those in the sham TEAS group (P<0.05). There was no statistically significant difference in the incidence of adverse reactions after surgery between the two groups (P>0.05). CONCLUSION TEAS can effectively improve both the postoperative acute pain and chronic pain in patients undergoing modified radical mastectomy for breast cancer, the mechanism may relate to inhibiting the inflammatory reaction.

The ability to localize sound sources rapidly allows human beings to efficiently understand the surrounding environment. Previous studies have suggested that there is an auditory "where" pathway in the cortex for processing sound locations. The neural activation in regions along this pathway encodes sound locations by opponent hemifield coding, in which each unilateral region is activated by sounds coming from the contralateral hemifield. However, it is still unclear how these regions interact with each other to form a unified representation of the auditory space. In the present study, we investigated whether functional connectivity in the auditory "where" pathway encoded sound locations during passive listening. Participants underwent functional magnetic resonance imaging while passively listening to sounds from five distinct horizontal locations (-90°, -45°, 0°, 45°, 90°). We were able to decode sound locations from the functional connectivity patterns of the "where" pathway. Furthermore, we found that such neural representation of sound locations was primarily based on the coding of sound lateralization angles to the frontal midline. In addition, whole-brain analysis indicated that functional connectivity between occipital regions and the primary auditory cortex also encoded sound locations by lateralization angles. Overall, our results reveal a lateralization-angle-based representation of sound locations encoded by functional connectivity patterns, which could add on the activation-based opponent hemifield coding to provide a more precise representation of the auditory space.

Alzheimer's disease (AD) is the major form of dementia in the elderly and is closely related to the toxic effects of microglia sustained activation. In AD, sustained microglial activation triggers impaired synaptic pruning, neuroinflammation, neurotoxicity, and cognitive deficits. Accumulating evidence has demonstrated that aberrant expression of deubiquitinating enzymes is associated with regulating microglia function. Here, we use RNA sequencing to identify a deubiquitinase YOD1 as a regulator of microglial function and AD pathology. Further study showed that YOD1 knockout significantly improved the migration, phagocytosis, and inflammatory response of microglia, thereby improving the cognitive impairment of AD model mice. Through LC-MS/MS analysis combined with Co-IP, we found that Myosin heavy chain 9 (MYH9), a key regulator maintaining microglia homeostasis, is an interacting protein of YOD1. Mechanistically, YOD1 binds to MYH9 and maintains its stability by removing the K48 ubiquitin chain from MYH9, thereby mediating the microglia polarization signaling pathway to mediate microglia homeostasis. Taken together, our study reveals a specific role of microglial YOD1 in mediating microglia homeostasis and AD pathology, which provides a potential strategy for targeting microglia to treat AD.

Gelsemium elegans (G. elegans) is an extremely poisonous plant that is widely distributed in southern China and southeastern Asia. G. elegans poisoning events occur frequently in southern China, and are therefore an urgent public health problem requiring multidisciplinary action. However, the toxic components and toxicological mechanisms remain unclear. Here, we describe a systematic investigation on the toxic components of G. elegans, resulting in the isolation and identification of 120 alkaloids. Based on acute toxicity screening, the structure-toxicity relationship of Gelsemium alkaloids was proposed for the first time. Moreover, gelsedine- and humantenine-type alkaloids were detected in the clinical blood sample, and were confirmed to be causative in the poisoning. The most toxic compound, gelsenicine (1), had selective inhibitory effects toward ventral respiratory group (VRG) neurons in the medulla, which is the main brain region controlling respiration in the central nervous system. Gelsenicine (1) strongly inhibited the firing of action potentials in VRG neurons through its ability to stimulate GABA_A receptors, the main receptors involved in inhibitory neurotransmission. Application of GABA_A receptor antagonists successively reversed action potential firing in gelsenicine (1)-treated VRG neurons. Importantly, the GABA_A receptor antagonists securinine and flumazenil significantly increased the survival of poisoned animals. Our findings provide insight into the components and mechanisms of G. elegans toxicity, and should assist the development of effective emergency treatments for G. elegans poisoning.
